Die Zuganker werden üblicherweise aus dem selben Material wie die Tankschalen gefertigt, insbesondere aus High Density Polyethylen (HDPE). Zuganker aus HDPE können bei der Herstellung der Tankschalen in diese eingeschweißt werden und sind daher kostengünstig zu fertigen.Plastic tanks, in particular pressure plastic fuel tanks (DKKB), are known to be equipped with tie rods for receiving tensile forces acting on the tank shells. The tie rods are usually made of the same material as the tank shells, in particular of high density polyethylene (HDPE). Tie rods made of HDPE can be welded into the tank shells during production and are therefore inexpensive to manufacture.

Es ist eine Aufgabe der Erfindung, Zuganker für Kunststofftanks zu verbessern und insbesondere Zuganker anzugeben, die verbesserte Langzeiteigenschaften unter Kraftstoffeinwirkung aufweisen, die weniger zu Verformungen neigen, die geringen Bauraumbedarf und geringes Gewicht haben und einfach herstellbar sind. Es ist auch eine Aufgabe der Erfindung einen verbesserten Kunststofftank und ein Verfahren zur Herstellung eines Kunststofftanks anzugeben.It is an object of the invention to improve tie rods for plastic tanks and in particular to provide tie rods which have improved long-term fuel properties, which are less prone to deformation, have low space requirements and low weight and are easy to produce. It is also an object of the invention to provide an improved plastic tank and a method of manufacturing a plastic tank.

Erfindungsgemäß weist ein Zuganker zwar Endflächen aus Kunststoff auf, und ist somit einfach mit dem Kunststofftank verbindbar, insbesondere mit der Tankschale des Kunststofftanks verschweißbar. Der Zuganker ist aber erfindungsgemäß nicht durchgängig aus Kunststoff gefertigt, sondern weist einen Mittelteil aus Metall auf, der weitaus weniger zu Verformungen bei längerer Einwirkung von Kraftstoff neigt als ein entsprechender Kunststoffteil.According to the invention, a tie rod, although plastic end surfaces, and is thus easily connectable to the plastic tank, in particular welded to the tank shell of the plastic tank. However, the tie rod is inventively not made of plastic, but has a middle part of metal, which is much less prone to deformation with prolonged exposure to fuel as a corresponding plastic part.
